Sets the data of a column using the provided argument bag. This is only meant for simple initialization for fragments that use UPROPERTY to expose properties. For complex initialization or when the fragment type is known it's recommended to use calls that work directly on the type for better performance and a wider range of configuration options. If the column couldn't be created or the column name points to a tag, then the result will contain only nullptrs.
